You can swap (crossgrade) the platform or language of a single-user product to a different platform or language of the same product. Swap (crossgrade) if you've been using the product on a particular platform or language, and then change your operating system or require a different language version.
You can swap only current versions, and only if the equivalent product is available for the new language or platform.
If you have a previous version, you cannot swap to a different platform or language of the previous version. Instead, it's necessary to upgrade. Place upgrade orders directly with Adobe Sales. (See the Contact Adobe page for your region for information on how to contact Sales.) Upgrade prices are applicable (if available for the product you are swapping), plus shipping costs.
